Description

포장용 스티로폼의 표면경화장치{Styrofoam surface hardening device for packaging}Styrofoam surface hardening device for packaging

개시되는 내용은 포장용 스티로폼의 표면경화장치에 관한 것으로, 더욱 상세하게는 가전제품 등을 포장하는 포장용 스티로폼을 제조하되 경도를 향상시킬 수 있도록 한 포장용 스티로폼의 표면경화장치에 관한 것이다. The disclosed subject matter relates to an apparatus for curing the surface of styrofoam for packaging, and more particularly, to an apparatus for curing the surface of styrofoam for packaging that is capable of improving hardness while manufacturing styrofoam for packaging for packaging home appliances.

본 명세서에서 달리 표시되지 않는 한, 이 섹션에 설명되는 내용들은 이 출원의 청구항들에 대한 종래 기술이 아니며, 이 섹션에 포함된다고 하여 종래 기술이라고 인정되는 것은 아니다.Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

스티로폼(STYROFOAM)은 발포폴리스티렌(Expandable PolyStyrene: EPS)에 펜탄이나 부탄과 같은 발포제를 첨가하여 가열 경화시킴과 동시에 기포를 발생시킨 발포수지이다.Styrofoam (STYROFOAM) is a foaming resin in which a foaming agent such as pentane or butane is added to Expandable Polystyrene (EPS) to heat and harden and at the same time generate bubbles.

스티로폼은 가벼울 뿐 아니라 내수성, 단열성, 방음성, 완충성이 좋기 때문에 다양한 제품 포장재의 소재로 널리 이용되고 있고, 완제품 또는 반제품상태의 대형 디스플레이장치의 포장재로도 쓰이고 있다.Styrofoam is widely used as a packaging material for various products because it is light and has good water resistance, heat insulation, sound insulation, and buffering properties, and is also used as a packaging material for large display devices in the finished or semi-finished state.

최근의 대형 디스플레이장치는 엘씨디(LCD: Liquid Crystal Display)패널이나 피디피(PDP: Plasma Display Panel)와 같은 디스플레이모듈을 채용하여 두께가 얇고 넓은 평판형태이기 때문에 이를 포장하기 위한 포장재도 제품을 수용하는 수용공간을 갖춘 넓은 패널형태로 제조되고 있다.Recent large display devices employ a display module such as LCD (Liquid Crystal Display) panel or PDP (Plasma Display Panel) to form a thin and wide flat panel. It is manufactured in the form of a wide panel with space.

그러나 스티로폼 재질의 포장재는 경도가 매우 약하기 때문에, 운송과정에서 외부로부터 충격 등이 가해질 경우 디스플레이장치에 의해 눌려지거나 긁히게 되면서 쉽게 손상되는 문제점이 있었다. However, since the packaging material made of Styrofoam has very weak hardness, there is a problem in that it is easily damaged as it is pressed or scratched by the display device when an impact or the like is applied from the outside during transportation.

이와 같은 포장재의 손상과정에서는 포장재로부터 미세한 스티로폼 분진이 발생될 경우 분진이 제품의 틈새로 침투되어 불량퓰을 높이는 원인이 될 수 있다.In the process of damage to the packaging material, if fine styrofoam dust is generated from the packaging material, the dust may penetrate into the gap of the product and increase the number of defective products.

종래에는 포장재의 표면에 충격에 의한 파손을 방지하기 위해 모서리보강제를 더 형성하였다. In the prior art, a corner reinforcement was further formed on the surface of the packaging material to prevent damage due to impact.

그러나 이런 경우 제조 공정이 증가함에 따라 비용이 상승하게 되고, 재?t용 대상이 안되므로 쓰레기 증가 및 처리의 문제점이 있었다. However, in this case, as the manufacturing process increases, the cost increases, and since it is not subject to reuse, there is a problem of increasing waste and processing.

Accordingly, the cooling water injected through the cooling water supply port 424 passes through the cooling water flow path 422 to have cooling heat in the plate 410 , and the cooling water is again recovered through the cooling water discharge port 426 .

이렇게 발생된 플레이트(410)의 냉각열은 성형틀(M) 및 성형제품, 즉 포장용 스티로폼(S)에 전달됨으로써 냉각작용을 하게 된다. The cooling heat of the plate 410 generated in this way is transferred to the mold M and the molded product, that is, the styrofoam for packaging (S), thereby performing a cooling action.

예를 들어 포장용 스티로폼(S)의 상면에 냉각작용을 실시하도록 함으로써 급격한 냉각에 의해 경화(S20)를 촉진시킬 수 있다(도 7 참조). For example, by providing a cooling action on the upper surface of the styrofoam for packaging (S), it is possible to accelerate the curing (S20) by rapid cooling (see FIG. 7).

상기 가열부(440)는, The heating unit 440 is

플레이트(410)의 타측 표면에 파여져서 형성되는 열전도 유로(443)와, A heat conduction passage 443 formed by being dug into the other surface of the plate 410, and

열전도 유로(443)에 공급되는 열매체유를 공급 및 회수하도록 커버부(600)에 결합된 열매체유 공급포트(445) 및 열매체유 회수포트(447)를 포함한다. It includes a heat medium oil supply port 445 and a heat medium oil recovery port 447 coupled to the cover part 600 to supply and recover the heat medium oil supplied to the heat conduction flow path 443 .

열매체유 공급포트(445) 및 열매체유 회수포트(447) 각각은 열전도 유로(443)와 통하도록 홀(449)이 형성된다(도 6 참조). A hole 449 is formed in each of the thermal oil supply port 445 and the thermal oil return port 447 to communicate with the heat conduction passage 443 (see FIG. 6 ).

상기 본체(200)의 표면에는 열을 전달하는 발열전달면(240)이 형성된다. 발열전달면(240)은 매끄러운 면으로 이루어져 성형틀(M)에 밀착되도록 한다. A heat transfer surface 240 for transferring heat is formed on the surface of the body 200 . The heat transfer surface 240 is made of a smooth surface so as to be in close contact with the mold (M).

따라서 열전도 유로(443)의 열선이 발열함으로써 플레이트(410)가 가열되고, 이렇게 가열된 열이 성형틀(M)에 전달된다.Accordingly, the plate 410 is heated by the heat wire of the heat conduction passage 443 being heated, and the heated heat is transferred to the mold M.

특히 성형틀(M)의 일부위에 집중적으로 열이 전달됨으로써 성형되는 포장용 스티로폼(S)의 표면을 가열시킴으로써 탄화(글레이징)되도록 하고, 이렇게 탄화된 표면은 경도를 갖는 표면층(S10)이 형성될 수 있다(도 7 참조). In particular, by heating the surface of the styrofoam (S) for packaging to be molded by intensive heat transfer to a part of the mold (M), the carbonized (glazing) surface is formed, and the surface layer (S10) having hardness can be formed There is (see Fig. 7).

따라서 포장용 스티로폼(S)의 표면에 내구성을 갖는 단단한 표면층이 형성될 수 있으므로 충격에 의한 부스러짐 또는 파손의 위험이 현저히 감소될 수 있다. Therefore, since a durable hard surface layer can be formed on the surface of the Styrofoam for packaging (S), the risk of crushing or damage due to impact can be significantly reduced.

비록 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.Although described with reference to the preferred embodiment, it will be readily recognized by those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, and all such changes and modifications fall within the scope of the appended claims. is self-evident
